The end is near for long-running Fox crime dramedy Bones; the question is how near — this season or next? During the network’s executive panel at TCA today, Fox chairman and CEO Dana Walden said she’s “really not 100% sure” about a pickup.

Stars David Boreanaz and Emily Deschanel need to re-up again, and I hear there have been some preliminary steps in that direction, a promising sign about efforts to extend the procedural. “We wouldn’t do the show without David and Emily,” Walden said after the session.

The decision will come down to 11 or 12 seasons for Bones. “It’s top of next-week business to start talking with the producers about whether this will be the end of its run or if it will go another season,” Walden said.

The talks are starting so early so the series “will be given plenty of time to start writing a meaningful ending to the show,” should there be no renewal. “They have such a loyal fanbase, and those fans deserve a satisfying ending.”

Bones, now in its 11th season, has been entangled in a legal web, with multiple complaints from Boreanaz and Deschanel and executive producer Barry Josephson. Walden stressed that while “the legal matter is not resolved, it will no impact on the decision-making for Season 12.”
